Precise cutting of fine wires and cables – even soft wires up to Ø1.6 mm

Narrow, non-bevelled head. Flush cutting also possible

Unlike diagonal cutters for domestic installations, this electronics diagonal cutter from Knipex is a real precision tool. With a length of 130 mm and weighing 110 g, it is extremely compact and lightweight, making it ideal for confined spaces, e.g. for PCBs and precision equipment. Cutting edge hardness approx. 57 HRC it cuts soft wires up to Ø1.6 mm. The short pliers head offers strong leverage. This makes it perfect for power delivery on the cutting edges and controlling manual force. Due to its design, the electronics diagonal cutter 77 21 130 is only suitable for soft and medium-hard wires. As the cutting edges are not bevelled, flush cutting is possible.

Zero-backlash box joint for high cutting quality and service life

The Knipex 77 21 130 electronics diagonal cutter has a box joint. The inside of both pliers handles is guided. This prevents tilting. Rivets only undergo shearing stress. Result: higher-quality cutting operations, long service life. The tool is oil-hardened, while the cutting edges are induction-hardened to approx. 57 HRC.

High Knipex quality standards and corrosion protection

The high-grade workmanship of Knipex electronics diagonal cutter 77 21 130 meets the requirements for electronics and precision equipment. Precision, functionality and reliability are paramount. Meticulously crafted, it is ideally suited to sensitive environments. Instead of a chrome finish it is mirror polished to prevent corrosion.
